Means carrying different superscripts in the same column are significantly different at P≤0.05 or highly significantly different at P<0.01. Means carrying the same superscripts in the same column are non-significantly different at P<0.05. TBC=Total bacterial count, TEC=Total Enterobacteriaceae count, TSC=Total Salmonella count, IgG=Immunoglobulin G, IgM=Immunoglobulin M, IgA=Immunoglobulin A, Log=Logarithm, SE=Standard error,
